The block has one fresh cote of paint on it since the engine build witch was performed 3 years ago. I removed most of the paint and can still see no numbers, the previous owner tried to find some as well before and after the machine shop worked on the motor, but could not find any and with the motor in the car pretty tough as other members have stated near impossible. I will check other codes as well. The power steering is the quick ratio unit, the intake is correct, the carb is correct as well, but everything in the car is a very high end restored conours level. The car has all original sheetmetal and pans etc. Caliofornia car most of it's life so all metal is original. Deep gove pulleys and 7 blade fan, radiator is not original but is the 21 inch core 3 rows, Wher can I find dates on the alternator and water pump?? does smog equipment have dates?? I was just told by other people who know these cars that as long as the engine casting dates are within a few months time before the cars build sounds right and should be the original motor, but some people say the norm is 1 to 6 weeks. So it seems nothing is set in stone and I am not going to pull my engine out and tear it apart. I have plenty of previuos owner docs and pics and history of the car to know what it is and the car has all original metal even original endura front bumper. I guess case closed and appreciate all the help.
Just for the record the car is a X33 D80 car, Hugger Orange with orange hounds tooth interior, black vinyl top, endura front bumper, power steering, console tach, cowl hood, blue light radio, rosewood wheel, chambered exhaust, black stripes of course.
